INTRODUCTION
All ParkerVision Horizons products are designed and manufactured by Direct2Data Technologies.
Products are fully compliant with IEEE 802.11b standards and are optimized to provide maximum
possible speed and bandwidth through your Internet connection for fastest uploads and downloads.
The distance capabilities of your wireless network equipment directly affect your signal quality. Distance
capabilities are usually stated in terms of outdoor, open eld reach. However, this reach is greatly
diminished indoors by walls, doors, construction techniques and appliances that may block the radio
signal. A wireless network adapter that tests outdoors at 200 feet could, in an indoor environment, provide
20 feet in one direction and as little as 5 or 10 feet in another direction. Factors such as building materials,
oor plans and furnishings can greatly impact the signal range, quality and rate of data transmission. The
extent to which your signal is affected varies greatly depending on your environment.
Wireless network products powered by D2D technology will provide better performance than other
products because they can achieve open eld distances of up to one mile, (when a D2D enabled adapter
is used in conjunction with a D2D enabled base station). The D2D adapter alone provides 3 to 7 times the
distance of other leading brands. This is sufcient to reach all rooms in most homes or small ofces.

This chapter introduces the main features of the ParkerVision Horizons 1500WR Wireless Router
1.1 Introduction
The ParkerVision Horizons 1500WR Wireless Router provides wireless connectivity. As an
Internet gateway, your 1500WR Wireless Router can share an Internet connection (through
a cable or xDSL modem) with multiple computers using SUA/NAT and DHCP. The 1500WR
Wireless Router offers highly secured wireless connectivity to your wired network with IEEE
802. lx, WEP data encryption and MAC address ltering.
The 1500WR Wireless Router is easy to install and congure. The embedded web-based
congurator and SNMP network management enables remote conguration and management of
your 1500WR Wireless Router.
1.2 Features of the ParkerVision Horizons PC 1500WR Wireless Router
The following are the essential features of the ParkerVision Horizons 1500WR Wireless Router .
4-Port Switch
A combination of switch and router makes your 1500WR Wireless Router a cost-effective and viable
network solution. You can connect up to four computers to the LAN ports on you 1500WR Wireless
Router without the cost of a hub.
10/100M Auto-negotiating Ethernet/Fast Ethernet Interface
This auto-negotiating feature allows the 1500WR Wireless Router to detect the speed of incoming
transmissions and adjust appropriately without manual intervention. It allows data transfer of either
10 Mbps or 100 Mbps in either half-duplex or full-duplex mode depending on your Ethernet network.
10/100M Auto-crossover Ethernet/Fast Ethernet Interface.
The LAN interface automatically adjusts to either a crossover or straight-through Ethernet
cable. 10/100 Mbps Ethernet WAN.
The 10/100 Mbps Ethernet WAN port attaches to the Internet via broadband modem or
router.
Reset Button
The 1500WR Wireless Router reset button is built into the side panel. Use this button to restore the
factory default password to 1234; IP address to 192.168.1.1, subnet mask to 255.255.255.0 and
DHCP sever enabled with a pool of 32 IP addresses starting at 192.168.1.33.
Brute-Force Password Guessing Protection
The 1500WR Wireless Router has a special protection mechanism to discourage brute-force
password guessing attacks on the 1500WR Wireless Router’s management interfaces. You
can specify a wait-time that must expire before entering a fourth password after three incorrect
passwords have been entered. Please see the appendix for details about this feature.

ParkerVision
1500WR Wireless Router LED
The blue 1500WR Wireless Router LED (also known as the Breathing LED) is on when the 1500WR Wireless
Router is on and blinks (or breaths) when data is being transmitted to/from its wireless stations. You may use
the web congurator to turn this LED off even when the 1500WR Wireless Router is on and data is being
transmitted/received.
802.11b Wireless LAN Standard
1500WR Wireless Router products containing the letter “B” in the model name, such as 1500WR Wireless Router
B-2000, 1500WR Wireless Router B-2000 v.2, comply with the 802.1 lb wireless standard.
The 802.1 lb data rate and corresponding modulation techniques are as follows. The modulation technique
denes how bits are encoded onto radio waves.
Output Power Management
Power Management is the ability to set the level of output power.
There may be interference or difculty with channel assignment when there is a high density of APs
within a coverage area. In this case you can lower the output power of each Wireless Router, thus
enabling you to place Wireless Routers closer together.
Limit the number of Client Connections
You may set a maximum number of wireless stations that may connect to the 1500WR Wireless
Router. This may be necessary if for example, there is difculty with channel assignment due to a high
density of APs within a coverage area.
SSL Passthrough
SSL (Secure Sockets Layer) uses a public key to encrypt data that’s transmitted over an SSL
connection. Both Netscape Navigator and Internet Explorer support SSL, and many web sites use the
protocol to obtain condential user information, such as credit card numbers. By convention, URLs
that require an SSL connection start with “https” instead of “http”. The 1500WR Wireless Router allows
SSL connections to take place through the 1500WR Wireless Router.
Firewall
The 1500WR Wireless Router employs a stateful inspection rewall with DoS (Denial of Service)
protection. By default, when the rewall is activated, all incoming trafc from the WAN to the LAN is
blocked unless it is initiated from the LAN. The 1500WR Wireless Router rewall supports TCP/UDP
inspection, DoS detection and prevention, real time alerts, reports and logs.
IEEE 802.1 x Network Security
The 1500WR Wireless Router supports the IEEE 802. lx standard to enhance user authentication.
Use the built-in user prole database to authenticate up to 32 users using MD5 encryption. Use an
EAP-compatible RADIUS (RFC2138,2139 - Remote Authentication Dial In User Service) server to
authenticate a limitless number of users using EAP (Extensible Authentication Protocol). EAP is an
authentication protocol that supports multiple types of authentication.
Wireless LAN MAC Address Filtering
Your 1500WR Wireless Router checks the MAC address of the wireless station against a list of
allowed or denied MAC addresses.
Universal Plug and Play (UPnP)
Using the standard TCP/IP protocol, the 1500WR Wireless Router and other UPnP-enabled devices
can dynamically join a network, obtain an IP address and convey its capabilities to other devices on
the network.
Horizons 1500WR Wireless 4-Port Router

ParkerVision
Dynamic DNS Support
With Dynamic DNS support, you can have a static hostname alias for a dynamic IP address, allowing
the host to be more easily accessible from various locations on the Internet. You must register for this
service.
PPPoE Support (RFC2516)
PPPoE (Point-to-Point Protocol over Ethernet) emulates a dial-up connection. It allows your ISP to
use their existing network conguration with newer broadband technologies such as ADSL. The PPPoE
driver on the 1500WR Wireless Router is transparent to the computers on the LAN, which see only
Ethernet and are not aware of PPPoE thus saving you from having to manage PPPoE clients on
individual computers.
PPTP Encapsulation
Point-to-Point Tunneling Protocol (PPTP) is a network protocol that enables secure transfer of data
from a remote client to a private server, creating a Virtual Private Network (VPN) using a TCP/IP-based
network. PPTP supports on-demand, multi-protocol and virtual private networking over public networks,
such as the Internet. Use PPTP to connect to a broadband modem to achieve access to high-speed
data networks via a familiar “dial-up networking” user interface.
Network Address Translation (NAT)
NAT (Network Address Translation - NAT, RFC 1631) allows the translations of multiple IP addresses
used within one network to different IP addresses known within another network.
NAT for Single-IP-address Internet Access
The 1500WR Wireless Router’s SUA (Single User Account) feature allows multiple-user Internet
access for the cost of a single IP account. NAT supports popular Internet applications such as MS
traceroute, CuSeeMe, IRC, RealPlayer, VDOLive, Quake, and PPTP. No conguration is needed
to support these applications.
DHCP (Dynamic Host Conguration Protocol)
DHCP (Dynamic Host Conguration Protocol) allows the individual clients (computers) to obtain the
TCP/IP conguration at start-up from a centralized DHCP server. The 1500WR Wireless Router has
built-in DHCP server capability enabled by default. It can assign IP addresses, an IP default gateway
and DNS servers to DHCP clients. The 1500WR Wireless Router also acts as a surrogate DHCP
server (DHCP Relay) where it relays IP address assignment from the actual real DHCP server to the
clients.
Multicast
Traditionally, IP packets are transmitted in two ways - unicast or broadcast. Multicast is a third way
to deliver IP packets to a group of hosts. IGMP (Internet Group Management Protocol) is the protocol
used to support multicast groups. The latest version is version 2 (see RFC 2236). The 1500WR
Wireless Router supports versions 1 and 2.
IP Alias
IP Alias allows you to partition a physical network into logical networks over the same Ethernet
interface. The 1500WR Wireless Router supports three logical LAN interfaces via its single physical
Ethernet LAN interface with the 1500WR Wireless Router itself as the gateway for each LAN network.
IP Policy Routing
IP Policy Routing provides a mechanism to override the default routing behavior and alter
packet forwarding based on the policies dened by the network administrator.
SNMP
SNMP (Simple Network Management Protocol) is a protocol used for exchanging management
information between network devices. SNMP is a member of the TCP/IP protocol suite. Your
Horizons 1500WR Wireless 4-Port Router
11
ParkerVision
1500WR Wireless Router supports SNMP agent functionality, which allows a manger station to manage and
monitor the SNMP - Continued
1500WR Wireless Router through the network. The 1500WR Wireless Router supports SNMP version
one (SNMPvl) and version two c (SNMPv2c).
Full Network Management
The embedded web congurator is an all-platform web-based utility that allows you to easily access the
1500WR Wireless Router’s management settings. Most functions of the 1500WR Wireless Router are
also software congurable via the SMT(System Management Terminal) interface. The SMT is a menu-
driven interface that you can access from a terminal emulator through the console port or over a telnet
connection.
• Logging and Tracing

well as conguration le backups and restoration.
Wireless Association List
With the Wireless Association List, you can see the list of the wireless stations that are currently using
the 1500WR Wireless Router to access your wired network.
Wireless LAN Channel Usage
The Wireless Channel Usage displays whether the radio channels are used by other wireless devices
within the transmission range of the 1500WR Wireless Router. This allows you to select the channel
with minimum interference for your 1500WR Wireless Router.

This chapter provides information on the Wizard Setup screens in the web Web Conguration Utility.
3.1 Wizard Setup Overview
The web Web Conguration Utility’s setup wizard helps you congure your 1500WR Wireless Router
for Internet access and set up wireless LAN.
3.1.1 Channel
The range of radio frequencies used by IEEE 802.1 lb wireless devices is called a “channel”.
Channels available depend on your geographical area. You may have a choice of channels (for
your region) so you should use a different channel than an adjacent AP (Wireless Router) to reduce
interference. Interference occurs when radio signals from different Wireless Routers overlap causing
interference and degrading performance.
Adjacent channels partially overlap however. To avoid interference due to overlap, your AP should be
on a channel at least ve channels away from a channel that an adjacent AP is using. For example,
if your region has 11 channels and an adjacent AP is using channel 1, then you need to select a
channel between 6 or 11.
The 1500WR Wireless Router’s “Scan” function is especially designed to automatically scan for a
channel with the least interference.
3.1.2 ESS ID
An Extended Service Set (ESS) is a group of Wireless Routers or wireless gateways connected to
a wired LAN on the same subnet. An ESS ID uniquely identies each set. All Wireless Routers or
wireless gateways and their associated wireless stations in the same set must have the same ESSID.
3.1.3 WEP Encryption
WEP (Wired Equivalent Privacy) encrypts data frames before transmitting over the wireless network.
WEP encryption scrambles the data transmitted between the wireless stations and the Wireless
Routers to keep network communications private. It encrypts unicast and multicast communications
in a network. Both the wireless stations and the Wireless Routers must use the same WEP key for
data encryption and decryption.

a remote client to a private server, creating a Virtual Private Network (VPN) using TCP/IP-based
networks.
PPTP supports on-demand, multi-protocol, and virtual private networking over public networks, such
as the Internet.
Refer to the appendix for more information on PPTP.
The 1500WR Wireless Router supports one PPTP server connection at any given time.

3.4.3 PPPoE Encapsulation
Point-to-Point Protocol over Ethernet (PPPoE) functions as a dial-up connection. PPPoE is an IETF
(Internet Engineering Task Force) draft standard specifying how a host personal computer interacts
with a broadband modem (for example xDSL, cable, wireless, etc.) to achieve access to high-speed
data networks. It preserves the existing Microsoft Dial-Up Networking experience and requires no
new learning or procedures.
For the service provider, PPPoE offers an access and authentication method that works with
existing access control systems (for instance, RADIUS). For the user, PPPoE provides a login and
authentication method that the existing Microsoft Dial-Up Networking software can activate, and
therefore requires no new learning or procedures for Windows users.
One of the benets of PPPoE is the ability to let end users access one of multiple network services,
a function known as dynamic service selection. This enables the service provider to easily create and
offer new IP services for specic users.
Operationally, PPPoE saves signicant effort for both the subscriber and the ISP/carrier, as it requires
no specic conguration of the broadband modem at the subscriber’s site.
By implementing PPPoE directly on the 1500WR Wireless Router (rather than individual computers),
the computers on the LAN do not need PPPoE software installed, since the 1500WR Wireless
Router does that part of the task. Furthermore, with NAT, all of the LAN’s computers will have Internet
access.
Refer to the appendix for more information on PPPoE, and to the next page for setup details.

3.5 Wizard Setup: WAN and DNS
The fourth wizard screen allows you to congure WAN IP address assignment, DNS server address
assignment and the WAN MAC address.
3.5.1 WAN IP Address Assignment
Every computer on the Internet must have a unique IP address. If your networks are isolated from the
Internet, for instance, only between your two branch ofces, you can assign any IP addresses to the
hosts without problems. However, the Internet Assigned Numbers Authority (IANA) has reserved the
following three blocks of IP addresses specically for private networks.
10.0.0.0 - 10.255.255.255
172.16.0.0 - 172.31.255.255
192.168.0.0 - 192.168.255.255
You can obtain your IP address from the IANA, from an ISP or have it assigned by a private network.
If you belong to a small organization and your Internet access is through an ISP, the ISP can provide
you with the Internet addresses for your local networks. On the other hand, if you are part of a much
larger organization, you should consult your network administrator for the appropriate IP addresses.
Regardless of your particular situation, do not create an arbitrary IP address;
always follow the guidelines above. For more information on address assignment,
please refer to RFC 1597, Address Allocation for Private Internets and RFC 1466,
Guidelines for Management of IP Address Space.
3.5.2 IP Address and Subnet Mask
Similar to the way houses on a street share a common street name, so too do computers on a LAN
share one common network number. Where you obtain your network number depends on your
particular situation. If the ISP or your network administrator assigns you a block of registered IP ad-
dresses, follow their instructions in selecting the IP addresses and the subnet mask.
If the ISP did not explicitly give you an IP network number, then most likely you have a single user
account and the ISP will assign you a dynamic IP address when the connection is established. If this
is the case, it is recommended that you select a network number from 192.168.0.0 to 192.168.255.0
and you must enable the Network Address Translation (NAT) feature of the 1500WR Wireless Router.
The Internet Assigned Number Authority (IANA) reserved this block of addresses specically for
private use; please do not use any other number unless you are told otherwise. Let’s say you select
192.168.1.0 as the network number; which covers 254 individual addresses, from 192.168.1.1 to
192.168.1.254 (zero and 255 are reserved). In other words, the rst three numbers specify the net-
work number while the last number identies an individual computer on that network.
Once you have decided on the network number, pick an IP address that is easy to remember, for
instance, 192.168.1.1, for your 1500WR Wireless Router, but make sure that no other device on your
network is using that IP address.
The subnet mask species the network number portion of an IP address. Your 1500WR Wireless
Router will compute the subnet mask automatically based on the IP address that you entered. You
don’t need to change the subnet mask computed by the 1500WR Wireless Router unless you are
instructed to do otherwise.

3.5.3 DNS Server Address Assignment
Use DNS (Domain Name System) to map a domain name to its corresponding IP address and vice
versa. For instance, the IP address of a web site with an URL of www.anycompany.com could be
192.168.3.1. The DNS server is extremely important because without it, you must know the IP ad-
dress of a computer before you can access it.
There are two ways that an ISP disseminates the DNS server addresses.
1. The ISP tells you the DNS server addresses, usually in the form of an information sheet, when
you sign up. If your ISP gives you DNS server addresses, enter them in the DNS Server elds
in DHCP Setup.
2. Leave the DNS Server elds in DHCP Setup blank (for example 0.0.0.0). The 1500WR Access
Point acts as a DNS proxy when this eld is blank.
3.5.4 WAN MAC Address
Every Ethernet device has a unique MAC (Media Access Control) address. The MAC address is as-
signed at the factory and consists of six pairs of hexadecimal characters, for example, 00:A0:C5:00:
00:02.
You can congure the WAN port’s MAC address by either using the factory default or cloning the
MAC address from a workstation on your LAN. Once it is successfully congured, the address will be
copied to the “rom” le (ZyNOS conguration le). It will not change unless you change the setting or
upload a different “rom” le.
ParkerVision recommends you clone the MAC address from a workstation on your LAN even if your
ISP does not require MAC address authentication.
Your 1500WR Wireless Router WAN port is always set at half-duplex mode as most cable/DSL mo-
dems only support half-duplex mode. Make sure your modem is in half-duplex mode. Your 1500WR
Wireless Router supports full duplex mode on the LAN side.
Example of Network Properties for LAN Servers with Fixed IP Addresses:
Choose an IP address 192.168.1.2-192.168.1.32; 192.168.1.65-192.168.1.254.
Subnet mask 255.255.255.0
Gateway (or default route) 192.168.1.1(1500WR Wireless RouterLANIP)

4.3 Dynamic DNS
Dynamic DNS allows you to update your current dynamic IP address with one or many dynamic DNS
services so that anyone can contact you (in NetMeeting, CU-SeeMe, etc.). You can also access your
FTP server or web site on your own computer using a DNS-like address (for instance myhost.dhs.org,
where myhost is a name of your choice) that will never change instead of using an IP address that
changes each time you reconnect. Your friends or relatives will always be able to call you even if they
don’t know your IP address.
First of all, you need to have registered a dynamic DNS account with www.dyndns.org. This is for
people with a dynamic IP from their ISP or DHCP server that would still like to have a DNS name. The
dynamic DNS service provider will give you a password or key.
4.3.1 DYNDNS Wildcard
Enabling the wildcard feature for your host causes *.yourhost.dyndns.org to be aliased to the same
IP address as yourhost.dyndns.org. This feature is useful if you want to be able to use, for example,
www.yourhost.dyndns.org and still reach your hostname.
If you have a private WAN IP address, then you cannot use Dynamic DNS.

Chapter 5
LAN Screens
This chapter describes how to congure LAN settings.
5.1 LAN Overview
Local Area Network (LAN) is a shared communication system to which many computers are at-
tached. The LAN screens can help you congure a LAN DHCP server, manage IP addresses, and
partition your physical network into logical networks.
Please see the Wizard Setup chapter for the background information about Primary and Secondary
DNS Server and IP Address and Subnet Mask.
5.2 LANs and WANs
A LAN is a computer network limited to the immediate area, usually the same building or oor of a
building. A WAN (Wide Area Network), on the other hand, is an outside connection to another net-
work or the Internet.
5.2.1 LANs, WANs and the 1500WR Wireless Router
The actual physical connection determines whether the 1500WR Wireless Router ports are LAN or
WAN ports. There are two separate IP networks, one inside, the LAN network; the other outside: the
WAN network as shown next:
Horizons 1500WR Wireless 4-Port Router
36
ParkerVision
5.3 DHCP Setup
DHCP (Dynamic Host Conguration Protocol, RFC 2131 and RFC 2132) allows individual clients to
obtain TCP/IP conguration at start-up from a server. You can congure the 1500WR Wireless Router
as a DHCP server or disable it. When congured as a server, the 1500WR Wireless Router provides
the TCP/IP conguration for the clients. If set to None, DHCP service will be disabled and you must
have another DHCP server on your LAN, or else the computer must be manually congured.
5.4 Factory LAN Defaults
The LAN parameters of the 1500WR Wireless Router are preset in the factory with the following val-
ues:
• IP address of 192.168.1.1 with subnet mask of 255.255.255.0 (24 bits)
• DHCP server enabled with 32 client IP addresses starting from 192.168.1.33.
IP Pool Setup
The 1500WR Wireless Router is pre-congured with a pool of 32 IP addresses starting from
192.168.1.33 to 192.168.1.64. This conguration leaves 31 IP addresses (excluding the 1500WR
Wireless Router itself) in the lower range for other server computers, for instance, servers for mail,
FTP, TFTP, web, etc., that you may have.
These parameters should work for the majority of installations. If your ISP gives you explicit DNS
server address(es), read the embedded web Web Conguration Utility help regarding what elds need
to be congured.
5.5 RIP Setup
RIP (Routing Information Protocol, RFC 1058 and RFC 1389) allows a router to exchange routing
information with other routers. RIP Direction controls the sending and receiving of RIP packets. When
set to:
1. Both - the 1500WR Wireless Router will broadcast its routing table periodically and incorporate the RIP
information that it receives.
2. In Only - the 1500WR Wireless Router will not send any RIP packets but will accept all RIP packets received.
3. Out Only - the 1500WR Wireless Router will send out RIP packets but will not accept any RIP packets received.
4. None - the 1500WR Wireless Router will not send any RIP packets and will ignore any RIP packets received.
RIP Version controls the format and the broadcasting method of the RIP packets that the 1500WR
Wireless Router sends (it recognizes both formats when receiving). RIP-1 is universally supported; but
RIP-2 carries more information. RIP-1 is probably adequate for most networks, unless you have an
unusual network topology.
Both RIP-2B and RIP-2M send routing data in RIP-2 format; the difference being that RIP-2B uses
subnet broadcasting while RIP-2M uses multicasting. Multicasting can reduce the load on non-router
machines since they generally do not listen to the RIP multicast address and so will not receive the
RIP packets. However, if one router uses multicasting, then all routers on your network must use multi-
casting, also.
By default, RIP Direction is set to Both and RIP Version to RIP-1.

5.6 Multicast
Traditionally, IP packets are transmitted in one of either two ways - Unicast (1 sender -1 recipient) or
Broadcast (1 sender - everybody on the network). Multicast delivers IP packets to a group of hosts on the
network - not everybody and not just 1.
IGMP (Internet Group Multicast Protocol) is a network-layer protocol used to establish membership in a
Multicast group - it is not used to carry user data. IGMP version 2 (RFC 2236) is an improvement over ver-
sion 1 (RFC 1112) but IGMP version 1 is still in wide use. If you would like to read more detailed information
about interoperability between IGMP version 2 and version 1, please see sections 4 and 5 of RFC 2236.
The class D IP address is used to identify host groups and can be in the range 224.0.0.0 to
239.255.255.255. The address 224.0.0.0 is not assigned to any group and is used by IP multicast comput-
ers. The address 224.0.0.1 is used for query messages and is assigned to the permanent group of all IP
hosts (including gateways).
All hosts must join the 224.0.0.1 group in order to participate in IGMP. The address 224.0.0.2 is assigned to
the multicast routers group.
The 1500WR Wireless Router supports both IGMP version 1 (IGMP-vl) and IGMP version 2 (IGMP-v2).
At start up, the 1500WR Wireless Router queries all directly connected networks to gather group member-
ship. After that, the 1500WR Wireless Router periodically updates this information. IP multicasting can be
enabled/disabled on the 1500WR Wireless Router LAN and/or WAN interfaces in the web Web Congura-
tion Utility (LAN; WAN). Select None to disable IP multicasting on these interfaces.

Chapter 6
Wireless Conguration
This chapter discusses how to congure the Wireless screens on the 1500WR Wireless Router.
6.1 Wireless LAN Overview
This section introduces the wireless LAN(WLAN) and some basic scenarios.
6.1.1 IBSS
An Independent Basic Service Set (IBSS), also called an Ad-hoc network, is the simplest WLAN
conguration. An IBSS is dened as two or more computers with wireless adapters within range of
each other that from an independent (wireless) network without the need of an Wireless Router (AP).
6.1.2 BSS
A Basic Service Set (BSS) exists when all communications between wireless stations or between a
wireless station and a wired network client go through one Wireless Router (AP).
Intra-BSS trafc is trafc between wireless stations in the BSS. When Intra-BSS is enabled, wireless
station A and B can access the wired network and communicate with each other. When Intra-BSS is
disabled, wireless station A and B can still access the wired network but cannot communicate with
each other.
The illustration on the next page describes a BSS setup.

ParkerVision
6.1.2 BSS - Continued
6.1.3 ESS
An Extended Service Set (ESS) consists of a series of overlapping BSSs, each containing an
Wireless Router, with each Wireless Router connected together by a wired network.
This wired connection between APs is called a Distribution System (DS). An ESSID (ESS
IDentication) uniquely identies each ESS. All Wireless Routers and their associated wireless
stations within the same ESS must have the same ESSID in order to communicate.

ParkerVision
6.2 Wireless LAN Basics
Refer also to the INSERT CHAPTER # for more background information on Wireless LAN features,
such as channels.
6.2.1 RTS/CTS
A hidden node occurs when two stations are within range of the same Wireless Router, but are not
within range of each other. The following gure illustrates a hidden node. Both stations (STA) are within
range of the Wireless Router (AP) or wireless gateway, but out-of-range of each other, so they cannot
“hear” each other, that is they do not know if the channel is currently being used. Therefore, they are
considered hidden from each other.
When station A sends data to the 1500WR Wireless Router, it might not know that station B is already
using the channel. If these two stations send data at the same time, collisions may occur when both
sets of data arrive at the AP at the same time, resulting in a loss of messages for both stations.
RTS/CTS is designed to prevent collisions due to hidden nodes. An RTS/CTS denes the biggest
size data frame you can send before an RTS (Request To Send)/CTS (Clear to Send) handshake is
invoked.
When a data frame exceeds the RTS/CTS value you set (between 0 to 2432 bytes), the station
that wants to transmit this frame must rst send an RTS (Request To Send) message to the AP for
permission to send it. The AP then responds with a CTS (Clear to Send) message to all other stations
within its range to notify them to defer their transmission. It also reserves and conrms with the
requesting station the time frame for the requested transmission.
Stations can send frames smaller than the specied RTS/CTS directly to the AP without the RTS
(Request To Send)/CTS (Clear to Send) handshake.
You should only congure RTS/CTS if the possibility of hidden nodes exists on your network and the
“cost” of resending large frames is more than the extra network overhead involved in the RTS (Request
To Send)/CTS (Clear to Send) handshake.
If the RTS/CTS value is greater than the Fragmentation Threshold value (see next), then the RTS
(Request To Send)/CTS (Clear to Send) handshake will never occur as data frames will be fragmented
before they reach RTS/CTS size.
Enabling the RTS Threshold causes redundant network overhead that could
negatively affect the throughput performance instead of providing a remedy.
Horizons 1500WR Wireless 4-Port Router
42
ParkerVision
6.2.2 Fragmentation Threshold
A Fragmentation Threshold is the maximum data fragment size (between 256 and 2432 bytes) that
can be sent in the wireless network before the 1500WR Wireless Router will fragment the packet into
smaller data frames.
A large Fragmentation Threshold is recommended for networks not prone to interference while you
should set a smaller threshold for busy networks or networks that are prone to interference.
If the Fragmentation Threshold value is smaller than the RTS/CTS value (see previously) you set, then
the RTS (Request To Send)/CTS (Clear to Send) handshake will never occur as data frames will be
fragmented before they reach RTS/CTS size.

Chapter 7
Wireless Security
This Chapter describes how to use the MAC Filter, 802. lx, Local User Database and RADIUS to
congure wireless security on your 1500WR Wireless Router.
7.1 Wireless Security Overview
Wireless security is vital to your network to protect wireless communication between wireless
stations, Wireless Routers and the wired network.
The gure below shows the possible wireless security levels on your 1500WR Wireless Router.
The highest security level relies on EAP (Extensible Authentication Protocol) for authentication and
utilizes dynamic WEP key exchange. It requires interaction with a RADIUS (Remote Authentication
Dial-In User Service) server either on the WAN or your LAN to provide authentication service for
wireless stations.
IMPORTANT - If you do not enable any wireless security on your 1500WR Wireless Router,
your network is accessible to any wireless networking device that is within range.
7.2 WEP Overview
WEP (Wired Equivalent Privacy) as specied in the IEEE 802.11 standard provides methods for both
data encryption and wireless station authentication.
7.2.1 Data Encryption
WEP provides a mechanism for encrypting data using encryption keys. Both the AP and the wireless
stations must use the same WEP key to encrypt and decrypt data. Your 1500WR Wireless Router
allows you to congure up to four 64-bit or 128-bit WEP keys, but only one key can be enabled at any
one time.
Horizons 1500WR Wireless 4-Port Router
45
ParkerVision
7.2.2 Authentication
Three different methods can be used to authenticate wireless stations to the network: Open System,
Shared Key, and Auto. The following gure illustrates the steps involved.
Open system authentication involves an unencrypted two-message procedure. A wireless station
sends an open system authentication request to the AP, which will then automatically accept and
connect the wireless station to the network. In effect, open system is not authentication at all as any
station can gain access to the network.
Shared key authentication involves a four-message procedure. A wireless station sends a shared key
authentication request to the AP, which will then reply with a challenge text message. The wireless
station must then use the AP’s default WEP key to encrypt the challenge text and return it to the AP,
which attempts to decrypt the message using the AP’s default WEP key. If the decrypted message
matches the challenge text, the wireless station is authenticated.
When your 1500WR Wireless Router’s authentication method is set to open system, it will only accept
open system authentication requests. The same is true for shared key authentication. However, when
it is set to auto authentication, the 1500WR Wireless Router will accept either type of authentication
request and the 1500WR Wireless Router will fall back to use open authentication if the shared key
does not match.

7.5 802.1 x Overview
The IEEE 802. lx standard outlines enhanced security methods for both the authentication of wireless
stations and encryption key management. Authentication can be done using the local user database
internal to the 1500WR Wireless Router (authenticate up to 32 users) or an external RADIUS server for
an unlimited number of users.
7.6 Introduction to RADIUS
RADIUS is based on a client-sever model that supports authentication and accounting, where Wireless
Router is the client and the server is the RADIUS server. The RADIUS server handles the following
tasks among others:
• Authentication - Determines the identity of the users.
• Accounting - Keeps track of the client’s network activity.
RADIUS user is a simple package exchange in which your 1500WR Wireless Router acts as a message
relay between the wireless station and the network RADIUS server.
Types of RADIUS Messages
The following types of RADIUS messages are exchanged between the Wireless Router and the
RADIUS server for user authentication:
• Access-Request - Sent by an Wireless Router requesting authentication.
• Access-Reject - Sent by a RADIUS server rejecting access.
• Access-Accept - Sent by a RADIUS server allowing access.
• Access-Challenge - Sent by a RADIUS server requesting more information in order to allow access.
The Wireless Router sends a proper response from the user and then sends another Access-
Request message.
The following types of RADIUS messages are exchanged between the Wireless Router and the
RADIUS server for user accounting:
• Accounting-Request - Sent by the Wireless Router requesting accounting.
• Accounting-Response - Sent by the RADIUS server to indicate that it has started or stopped
accounting.
In order to ensure network security, the Wireless Router and the RADIUS server use a shared secret
key, which is a password, they both know. The key is not sent over the network. In addition to the shared
key, password information exchanged is also encrypted to protect the wired network from unauthorized
access.
7.6.1 EAP Authentication Overview
EAP (Extensible Authentication Protocol) is an authentication protocol that runs on top of the
IEEE802.1x transport mechanism in order to support multiple types of user authentication. By using
EAP to interact with an EAP-compatible RADIUS server, the Wireless Router helps a wireless station
and a RADIUS server perform authentication.
The type of authentication you use depends on the RADIUS server or the AP. The 1500WR
Wireless Router supports EAP-TLS, EAP-TTLS and DEAP with RADIUS. Refer to the Types of EAP
Authentication appendix for descriptions on the four common types.
Your 1500WR Wireless Router supports EAP-MD5 (Message-Digest Algorithm 5) with the local user
database and RADIUS. The following gure shows an overview of authentication when you specify a
RADIUS server on your Wireless Router.
Horizons 1500WR Wireless 4-Port Router
50
ParkerVision
7.6.1 EAP Authentication Overview - Continued
The details below provide a general description of how IEEE 802. lx EAP authentication works. For an
example list of EAP-MD5 authentication steps, see the IEEE 802.lx appendix.
• The wireless station sends a “start” message to the 1500WR Wireless Router.
• The 1500WR Wireless Router sends a “request identity” message to the wireless station for identity
information.
• The wireless station replies with identity information, including username and password.
• The RADIUS server checks the user information against its user prole database and determines
whether or not to authenticate the wireless station.
7.7 Dynamic WEP Key Exchange
The AP maps a unique key that is generated with the RADIUS server. This key expires when the
wireless connection times out, disconnects or reauthentication times out. A new WEP key is generated
each time reauthentication is performed.
If this feature is enabled, it is not necessary to congure a default encryption key in the Wireless
screen. You may still congure and store keys here, but they will not be used while Dynamic WEP is
enabled.
To use Dynamic WEP, enable and congure the RADIUS server (see section 7.11) and enable
Dynamic WEP Key Exchange in the 802.lx screen. Ensure that the wireless station’s EAP type is
congured to one of the following:
• EAP-TLS
• EAP-TTLS
• PEAP
EAP-MD5 cannot be used with Dynamic WEP Key Exchange.

7.8 Introduction to Local User Database
By storing user proles locally on the 1500WR Wireless Router, your 1500WR Wireless Router is able
to authenticate wireless users without interacting with a network RADIUS server. However, there is a
limit on the number of users you may authenticate in this way.

8.3 TCP/IP Priority (Metric)
The metric represents the “cost of transmission”. A router determines the best route for transmission by
choosing a path with the lowest “cost”. RIP routing uses hop count as the measurement of cost, with a
minimum of “ 1” for directly connected networks. The number must be between “ 1” and “ 15”; a number
greater than “15” means the link is down. The smaller the number, the lower the “cost”.
The metric sets the priority for the 1500WR Wireless Router’s routes to the Internet, if any two of the
default routes have the same metric.

Type the IP address of the remote network or gateway. The gateway is an
immediate neighbor of your 1500WR Wireless Router that will forward the packet
to the destination. On the LAN, the gateway must be a router on the same
segment as your 1500WR Wireless Router; over the WAN, the gateway must be
the IP address of one of the remote nodes.
Remote IP Subnet Mask (PPPoE
and PPTP encapsulation)
When using a LAN to LAN application, type the IP subnet mask of the
destination network. If you need to specify a route to a single host, use a
subnet mask of 255.255.255.255, in the subnet mask eld, to force the
network number to be identical to the host ID.
Network Address Translation Network Address Translation (NAT) allows the translation of an Internet protocol
address used within one network to a different IP address known within another
network.
SUA (Single User Account) is a subset of NAT that supports two types of
mapping: Many-to-One and Server. When you select this option the 1500WR
Wireless Router will use Address Mapping Set 255 in the SMT.
Choose SUA Only if you have just one public WAN IP address for your 1500WR
Wireless Router. Choose Full Feature if you have multiple public WAN IP
addresses for your 1500WR Wireless Router. For more information about NAT
refer to the MAT chapter in this User’s Guide.
Metric (PPPoE and PPTP only) Type a number that approximates the cost for this link. Metric represents the “cost”
of transmission for routing purposes. IP routing uses hop count as the measurement
of cost, with a minimum of 1 for directly connected networks. The number need not
be precise, but it must be between 1 and 15. In practice, 2 or 3 is usually a good
number.
Private (PPPoE and PPTP
only)
This parameter determines if the 1500WR Wireless Router will include the route
to this remote node in its RIP broadcasts. If select Yes, this route is kept private
and not included in RIP broadcast. If select No, the route to this remote node will
be propagated to other hosts through RIP broadcasts.

The following table descirbes the labels on the screen on the preceeding pages.
LABEL DESCRIPTION
RIP Direction RIP (Routing Information Protocol) allows a router to exchange routing information with other
routers. The RIP Direction eld controls the sending and receiving of RIP packets.
Choose Both, None, In Only or Out Only. When set to Both or Out Only, the 1500WR Wireless
Router will broadcast its routing table periodically.
When set to Both or In Only, the 1500WR Wireless Router will incorporate RIP information that it
receives.
When set to None, the 1500WR Wireless Router will not send any RIP packets and will ignore any
RIP packets received.
By default, RIP Direction is set to Both.
RIP Version The RIP Version eld controls the format and the broadcasting method of the RIP packets that the
1500WR Wireless Router sends (it recognizes both formats when receiving).
Choose RIP-1, RIP-2B or RIP-2M.
RIP-1 is universally supported; but RIP-2 carries more information. RIP-1 is probably adequate for
most networks, unless you have an unusual network topology. Both RIP-2B and RIP-2M sends the
routing data in RIP-2 format; the difference being that RIP-2B uses subnet broadcasting while RIP-
2M uses multicasting. Multicasting can reduce the load on non-router machines since they generally
do not listen to the RIP multicast address and so will not receive the RIP packets. However, if one
router uses multicasting, then all routers on your network must use multicasting, also. By default,
the RIP Version eld is set to RIP-1.
Multicast Choose None (default), IGMP-V1 or IGMP-V2. IGMP (Internet Group Multicast Protocol) is a
session-layer protocol used to establish membership in a Multicast group - it is not used to carry
user data. IGMP version 2 (RFC 2236) is an improvement over version 1 (RFC 1112) but IGMP
version 1 is still in wide use. If you would like to read more detailed information about interoperability
between IGMP version 2 and version 1, please see sections 4 and 5 of RFC 2236.
Windows Networking (NetBIOS over TCP/IP): NetBIOS (Network Basic Input/Output System) are TCP or UDP broadcast
packets that enable a computer to connect to and communicate with a LAN. For some dial-up services such as PPPoE or
PPTP, NetBIOS packets cause unwanted calls.

Chapter 9
Single User Account (SUA) / Network Address Translation (NAT)
This chapter discusses how to congure SUA/NAT on the 1500WR Wireless Router.
9.1 NAT Overview
NAT (Network Address Translation - NAT, RFC 1631) is the translation of the IP address of a host in a
packet. For example, the source address of an outgoing packet, used within one network is changed
to a different IP address known within another network.
9.1.1 NAT Denitions
Inside/outside denotes where a host is located relative to the 1500WR Wireless Router For example,
the computers of your subscribers are the inside hosts, while the web servers on the Internet are the
outside hosts.
Global/local denotes the IP address of a host in a packet as the packet traverses a router. For
example, the local address refers to the IP address of a host when the packet is in the local network,
while the global address refers to the IP address of the host when the same packet is traveling in the
WAN side.
Note that inside/outside refers to the location of a host, while global/local refers to the IP address
of a host used in a packet. Thus, an inside local address (ILA) is the IP address of an inside host in
a packet when the packet is still in the local network, while an inside global address (IGA) is the IP
address of the same inside host when the packet is on the WAN side.
The following table summarizes this information.
TERM DESCRIPTION
Inside This refers to the host on the LAN.
Outside This refers to the host on the WAN.
Local This refers to the packet address (source or destination) as the packet travels on the LAN.
Global This refers to the packet address (source or destination) as the packet travels on the WAN.
NAT never changes the IP address (either local or global) of an outside host.
Horizons 1500WR Wireless 4-Port Router

ParkerVision
9.1 NAT Overview - Continued
9.1.2 What NAT Does
In the simplest form, NAT changes the source IP address in a packet received from a subscriber (the
inside local address) to another (the inside global address) before forwarding the packet to the WAN
side. When the response comes back, NAT translates the destination address (the inside global ad-
dress) back to the inside local address before forwarding it to the original inside host. Note that the IP
address (either local or global) of an outside host is never changed.
The global IP addresses for the inside hosts can be either static or dynamically assigned by the ISP.
In addition, you can designate servers (for example a web server and a telnet server) on your local
network and make them accessible to the outside world. Although you can make designated servers
on the LAN accessible to the outside world, it is strongly recommended that you attach those servers
to the DMZ port instead. If you do not dene any servers (for Many-to-One and Many-to-Many Over-
load mapping), NAT offers the additional benet of rewall protection. With no servers dened, your
1500WR Wireless Router lters out all incoming inquiries, thus preventing intruders from probing your
network. For more information on IP address translation, refer to RFC 1631, The IP Network Address
Translator (NAT).
9.1.3 How NAT Works
Each packet has two addresses - a source address and a destination address. For outgoing packets,
the ILA (Inside Local Address) is the source address on the LAN, and the IGA (Inside Global Address)
is the source address on the WAN. For incoming packets, the ILA is the destination address on the
LAN, and the IGA is the destination address on the WAN. NAT maps private (local) IP addresses to
globally unique ones required for communication with hosts on other networks. It replaces the original
IP source address (and TCP or UDP source port numbers for Many-to-One and Many-to-Many Over-
load NAT mapping) in each packet and then forwards it to the Internet. The 1500WR Wireless Router
keeps track of the original addresses and port numbers so incoming reply packets can have their origi-
nal values restored.
The following gure illustrates this.

9.1.4 NAT Application

9.1.5 NAT Mapping Types
NAT supports ve types of IP/port mapping. They are:
> One to One: In One-to-One mode, the 1500WR Wireless Router maps one local IP address to one
global IP address.
> Many to One: In Many-to-One mode, the 1500WR Wireless Router maps multiple local IP address-
es to one global IP address. This is equivalent to SUA (i.e., PAT, port address translation), ParkerVi-
sion’s Single User Account feature (the SUA Only option).
> Many to Many Overload: In Many-to-Many Overload mode, the 1500WR Wireless Router maps the
multiple local IP addresses to shared global IP addresses.
> Many One to One: In Many-One-to-One mode, the 1500WR Wireless Router maps each local IP
address to a unique global IP address.
> Server: This type allows you to specify inside servers of different services behind the NAT to be
accessible to the outside world.
Port numbers do not change for One-to-One and Many-One-to-One NAT mapping types.
The following table summarizes these types.

9.1.6 SUA (Single User Account) Versus NAT
SUA (Single User Account) is a ParkerVision implementation of a subset of NAT that supports two
types of mapping, Many-to-One and Server. The 1500WR Wireless Router also supports Full Feature
NAT to map multiple global IP addresses to multiple private LAN IP addresses of clients or servers us-
ing mapping types. Select either SUA Only or Full Feature in WAN IP.
9.2 SUA Server
An SUA server set is a list of inside (behind NAT on the LAN) servers, for example, web or FTP, that
you can make visible to the outside world even though SUA makes your whole inside network appear
as a single computer to the outside world.
You may enter a single port number or a range of port numbers to be forwarded, and the local IP ad-
dress of the desired server. The port number identies a service; for example, web service is on port
80 and FTP on port 21. In some cases, such as for unknown services or where one server can support
more than one service (for example both FTP and web service), it might be better to specify a range of
port numbers. You can allocate a server IP address that corresponds to a port or a range of ports.
Many residential broadband ISP accounts do not allow you to run any server processes (such as a
Web or FTP server) from your location. Your ISP may periodically check for servers and may suspend
your account if it discovers any active services at your location. If you are unsure, refer to your ISP.
Default Server IP Address
In addition to the servers for specied services, NAT supports a default server IP address. A default
server receives packets from ports that are not specied in this screen.
If you do not assign a Default Server IP Address, then all packets received for ports
not specied in this screen will be discarded.
9.2.1 Port Forwarding: Services and Port Numbers
In addition to the servers for specied services, NAT supports a default server. A service request that
does not have a server explicitly designated for it is forwarded to the default server. If the default server
is not dened, the service request is simply discarded.
Many residential broadband ISP accounts do not allow you to run any server
processes (such as a Web or FTP server) from your location. Your ISP may
periodically check for servers and may suspend your account if it discovers any
active services at your location. If you are unsure, refer to your ISP.

9.4 Conguring Address Mapping
Ordering your rules is important because the 1500WR Wireless Router applies the rules in the order
that you specify. When a rule matches the current packet, the 1500WR Wireless Router takes the cor-
responding action and the remaining rules are ignored. If there are any empty rules before your new
congured rule, your congured rule will be pushed up by that number of empty rules. For example, if
you have already congured rules 1 to 6 in your current set and now you congure rule number 9. In
the set summary screen, the new rule will be rule 7, not 9. Now if you delete rule 4, rules 5 to 7 will be
pushed up by 1 rule, so old rules 5,6 and 7 become new rules 4, 5 and 6.

Static Route
This chapter shows you how to congure static routes for your 1500WR Wireless Router.
10.1 Static Route Overview
Each remote node species only the network to which the gateway is directly connected, and the
1500WR Wireless Router has no knowledge of the networks beyond. For instance, the 1500WR
Wireless Router knows about network N2 in the following gure through remote node Router 1.
However, the 1500WR Wireless Router is unable to route a packet to network N3 because it doesn’t
know that there is a route through the same remote node Router 1 (via gateway Router 2). The static
routes are for you to tell the 1500WR Wireless Router about the networks beyond the remote nodes.

Introduction to Firewalls
This chapter gives some background information on rewalls and introduces the 1500WR Wireless
Router rewall.
11.1 Firewall Overview
Originally, the term Firewall referred to a construction technique designed to prevent the spread of
re from one room to another. The networking term “rewall” is a system or group of systems that
enforces an access-control policy between two networks. It may also be dened as a mechanism
used to protect a trusted network from an untrusted network. Of course, rewalls cannot solve every
security problem. A rewall is one of the mechanisms used to establish a network security perimeter in
support of a network security policy. It should never be the only mechanism or method employed. For
a rewall to guard effectively, you must design and deploy it appropriately. This requires integrating
the rewall into a broad information-security policy. In addition, specic policies must be implemented
within the rewall itself.
11.2 Types of Firewalls
There are three main types of rewalls:
1. Packet Filtering Firewalls
2. Application-level Firewalls
3. Stateful Inspection Firewalls
11.2.1 Packet Filtering Firewalls
Packet ltering rewalls restrict access based on the source/destination computer network address
of a packet and the type of application.
11.2.2 Application-level Firewalls
Application-level rewalls restrict access by serving as proxies for external servers. Since they use
programs written for specic Internet services, such as HTTP, FTP and telnet, they can evaluate
network packets for valid application-specic data. Application-level gateways have a number of
general advantages over the default mode of permitting application trafc directly to internal hosts:
i. Information hiding prevents the names of internal systems from being made known via DNS to
outside systems, since the application gateway is the only host whose name must be made known to
outside systems.
ii. Robust authentication and logging pre-authenticates application trafc before it reaches internal
hosts and causes it to be logged more effectively than if it were logged with standard host logging.
Filtering rules at the packet ltering router can be less complex than they would be if the router needed
to lter application trafc and direct it to a number of specic systems. The router need only allow
application trafc destined for the application gateway and reject the rest.

11.2.3 Stateful Inspection Firewalls
Stateful inspection rewalls restrict access by screening data packets against dened access rules.
They make access control decisions based on IP address and protocol. They also “inspect” the session
data to assure the integrity of the connection and to adapt to dynamic protocols. These rewalls
generally provide the best speed and transparency; however, they may lack the granular application
level access control or caching that some proxies support. See section 11.5 for more information on
Stateful Inspection.
Firewalls, of one type or another, have become an integral part of standard security solutions for
enterprises.
11.3 Introduction to ParkerVision’s Firewall
The 1500WR Wireless Router rewall is a stateful inspection rewall and is designed to protect against
Denial of Service attacks when activated (in SMT menu 21.2 or in the web Web Conguration Utility).
The 1500WR Wireless Router’s purpose is to allow a private Local Area Network (LAN) to be securely
connected to the Internet. The 1500WR Wireless Router can be used to prevent theft, destruction and
modication of data, as well as log events, which may be important to the security of your network. The
1500WR Wireless Router also has packet-ltering capabilities.
11.4 Denial of Service
Denials of Service (DoS) attacks are aimed at devices and networks with a connection to the Internet.
Their goal is not to steal information, but to disable a device or network so users no longer have access
to network resources. The 1500WR Wireless Router is pre-congured to automatically detect and
thwart all known DoS attacks.

11.4.1 Basics
Computers share information over the Internet using a common language called TCP/IP. TCP/IP, in
turn, is a set of application protocols that perform specic functions. An “extension number”, called the
“TCP port” or “UDP port” identies these protocols, such as HTTP (Web), FTP (File Transfer Protocol),
POP3 (E-mail), etc. For example, Web trafc by default uses TCP port 80.
When computers communicate on the Internet, they are using the client/server model, where the server
“listens” on a specic TCP/UDP port for information requests from remote client computers on the
network. For example, a Web server typically listens on port 80. Please note that while a computer may
be intended for use over a single port, such as Web on port 80, other ports are also active. If the person
conguring or managing the computer is not careful, a hacker could attack it over an unprotected port.
Some of the most common IP ports are:
11.4.2 Types of DoS Attacks
There are four types of DoS attacks:
1. Those that exploit bugs in a TCP/IP implementation.
2. Those that exploit weaknesses in the TCP/IP specication.
3. Brute-force attacks that ood a network with useless data.
4. IP Spoong.
1. “Ping of Death” and “Teardrop” attacks exploit bugs in the TCP/IP implementations of various
computer and host systems.
1-a Ping of Death uses a “ping” utility to create an IP packet that exceeds the maximum 65,536
bytes of data allowed by the IP specication. The oversize packet is then sent to an unsuspecting
system. Systems may crash, hang or reboot.
1-b Teardrop attack exploits weaknesses in the reassembly of IP packet fragments. As data
is transmitted through a network, IP packets are often broken up into smaller chunks. Each
fragment looks like the original IP packet except that it contains an offset eld that says, for
instance, “This fragment is carrying bytes 200 through 400 of the original (non fragmented) IP
packet.” The Teardrop program creates a series of IP fragments with overlapping offset elds.
When these fragments are reassembled at the destination, some systems will crash, hang, or
reboot.
2. Weaknesses in the TCP/IP specication leave it open to “SYN Flood” and “LAND” attacks. These
attacks are executed during the handshake that initiates a communication session between two
applications.
Horizons 1500WR Wireless 4-Port Router
84
ParkerVision
11.4.2 Types of DoS Attacks - Continued
Under normal circumstances, the application that initiates a
session sends a SYN (synchronize) packet to the receiving
server. The receiver sends back an ACK (acknowledgment)
packet and its own SYN, and then the initiator responds
with an ACK (acknowledgment). After this handshake, a
connection is established.
2. a) A SYN Attack oods a targeted system with a series
of SYN packets. Each packet causes the targeted system
to issue a SYN-ACK response. While the targeted system
waits for the ACK that follows the SYN-ACK, it queues up
all outstanding SYN-ACK responses on what is known as
a backlog queue. SYN-ACKs are moved off the queue only
when an ACK comes back or when an internal timer (which
is set at relatively long intervals) terminates the three-way
handshake. Once the queue is full, the system will ignore all
incoming SYN requests, making the system unavailable for
legitimate users.
2. b) In a LAND Attack, hackers ood SYN packets into the
network with a spoofed source IP address of the targeted
system. This makes it appear as if the host computer sent
the packets to itself, making the system unavailable while the
target system tries to respond to itself.
3. A brute-force attack, such as a “Smurf’ attack, targets
a feature in the IP specication known as directed or subnet
broadcasting, to quickly ood the target network with useless
data. A Smurf hacker oods a router with Internet Control
Message Protocol (ICMP) echo request packets (pings).
Since the destination IP address of each packet is the
broadcast address of the network, the router will broadcast
the ICMP echo request packet to all hosts on the network.
If there are numerous hosts, this will create a large amount
of ICMP echo request and response trafc. If a hacker chooses to spoof the source IP address of the
ICMP echo request packet, the resulting ICMP trafc will not only clog up the “intermediary” network,
but will also congest the network of the spoofed source IP address, known as the “victim” network.
This ood of broadcast trafc consumes all available bandwidth, making communications impossible.

11.4.2 Types of DoS Attacks - Continued
ICMP Vulnerability
ICMP is an error-reporting protocol that works in concert with IP. The following ICMP types trigger an
alert:
Illegal Commands (NetBIOS and SMTP)
The only legal NetBIOS commands are the following - all others are illegal.
All SMTP commands are illegal except for those displayed in the following table.
Traceroute
Traceroute is a utility used to determine the path a packet takes between two endpoints. Sometimes
when a packet lter rewall is congured incorrectly an attacker can traceroute the rewall gaining
knowledge of the network topology inside the rewall.
4. Often, many DoS attacks also employ a technique known as “IP Spoong” as part of their attack.
IP Spoong may be used to break into systems, to hide the hacker’s identity, or to magnify the effect
of the DoS attack. IP Spoong is a technique used to gain unauthorized access to computers by
tricking a router or rewall into thinking that the communications are coming from within the trusted
network. To engage in IP spoong, a hacker must modify the packet headers so that it appears that the
packets originate from a trusted host and should be allowed through the router or rewall. The 1500WR
Wireless Router blocks all IP Spoong attempts.

11.5 Stateful Inspection
Stateful inspection means the 1500WR Wireless Router records packet information, such as port
number and source/destination addresses and then allows or denies the response depending on your
rewall rules.
The default rules allow LAN-to-WAN trafc and deny trafc initiated from WAN-to-LAN.
The previous gure shows the 1500WR Wireless Router’s default rewall rules in action as well as
demonstrates how stateful inspection works. User A can initiate a Telnet session from within the LAN
and responses to this request are allowed. However other Telnet trafc initiated from the WAN is
blocked.

Chapter 12
Firewall Screens
This chapter shows you how to congure your 1500WR Wireless Router rewall.
12.1 Access Methods
The web Web Conguration Utility is, by far, the most comprehensive rewall conguration tool your
1500WR Wireless Router has to offer. For this reason, it is recommended that you congure your
rewall using the web Web Conguration Utility. SMT screens allow you to activate the rewall.
12.2 Firewall Policies Overview
Firewall rules are grouped based on the direction of travel of packets to which they apply:
• LAN to LAN/1500WR Wireless Router
• WAN to LAN
• LAN to WAN
• WAN to WAN/1500WR Wireless Router
By default, the 1500WR Wireless Router’s stateful packet inspection allows packets traveling in the
following directions:
• LAN to LAN/1500WR Wireless Router
This allows computers on the LAN to manage the 1500WR Wireless Router and communicate
between networks or subnets connected to the LAN interface.
• LAN to WAN
By default, the 1500WR Wireless Router’s stateful packet inspection blocks packets traveling in the
following directions:
• WAN to LAN
• WAN to WAN/1500WR Wireless Router
This prevents computers on the WAN from using the 1500WR Wireless Router as a gateway to
communicate with other computers on the WAN and/or managing the 1500WR Wireless Router.
You may dene additional rules and sets or modify existing ones but please exercise extreme caution
in doing so.
Horizons 1500WR Wireless 4-Port Router
88
ParkerVision
12.2 Firewall Policies Overview - Continued
If you congure rewall rules without a good understanding of how they work, you might
inadvertently introduce security risks to the rewall and to the protected network. Make sure
you test your rules after you congure them.
For example, you may create rules to:
• Block certain types of trafc, such as IRC (Internet Relay Chat), from the LAN to the Internet.
• Allow certain types of trafc, such as Lotus Notes database synchronization, from specic hosts
on the Internet to specic hosts on the LAN.
• Allow everyone except your competitors to access a Web server.
• Restrict use of certain protocols, such as Telnet, to authorized users on the LAN.
These custom rules work by comparing the Source IP address, Destination IP address and IP protocol
type of network trafc to rules set by the administrator. Your customized rules take precedence and
override the 1500WR Wireless Router’s default rules.
12.3 Rule Logic Overview
Study these points carefully before conguring rules.
12.3.1 Rule Checklist
1. State the intent of the rule. For example, “This restricts all IRC access from the LAN to the
Internet.” Or, “This allows a remote Lotus Notes server to synchronize over the Internet to an
inside Notes server.”
2. Is the intent of the rule to forward or block trafc?
3. What direction of trafc does the rule apply to (refer to 12.2)1
4. What IP services will be affected?
5. What computers on the Internet will be affected? The more specic, the better. For example, if
trafc is being allowed from the Internet to the LAN, it is better to allow only certain machines
on the Internet to access the LAN.
12.3.2 Security Ramications
Once the logic of the rule has been dened, it is critical to consider the security ramications created by
the rule:
1. Does this rule stop LAN users from accessing critical resources on the Internet? For example, if
IRC is blocked, are there users that require this service?
2. Is it possible to modify the rule to be more specic? For example, if IRC is blocked for all users,
will a rule that blocks just certain users be more effective?
3. Does a rule that allows Internet users access to resources on the LAN create a security
vulnerability? For example, if FTP ports (TCP 20,21) are allowed from the Internet to the LAN,
Internet users may be able to connect to computers with running FTP servers.
4. Does this rule conict with any existing rules?
Once these questions have been answered, adding rules is simply a matter of plugging the information
into the correct elds in the web Web Conguration Utility screensSource Address

12.3.3 Key Fields For Conguring Rules Action
Should the action be to Block or Forward?
“Block” means the rewall silently discards the packet.
Service
Select the service from the Service scrolling list box. If the service is not listed, it is necessary to rst
dene it. See section 12.5.3 for more information on predened services.
Source Address
What is the connection’s source address; is it on the LAN or WAN? Is it a single IP, a range of Ips or a
subnet?
Destination Address
What is the connection’s destination address; is it on the LAN or WAN? Is it a single IP, a range of Ips
or a subnet?
12.4 Connection Direction Examples
This section describes examples for rewall rules for connections going from LAN to WAN and from
WAN to LAN.
LAN to LAN/1500WR Wireless Router and WAN to WAN/1500WR Wireless Router rules apply to
packets coming in on the associated interface (LAN or WAN respectively). LAN to LAN/1500WR
Wireless Router means policies for LAN-to-1500WR Wireless Router (the policies for managing the
1500WR Wireless Router through the LAN interface) and policies for LAN-to-LAN (the policies that
control routing between two subnets on the LAN).
12.4.1 LAN to WAN Rules
The default rule for LAN to WAN trafc is that all users on the LAN are allowed non-restricted access to
the WAN. When you congure a LAN to WAN rule, you in essence want to limit some or all users from
accessing certain services on the WAN. See the following gure.
Horizons 1500WR Wireless 4-Port Router
90
ParkerVision
12.4.2 WAN to LAN Rules
The default rule for WAN to LAN trafc blocks all incoming connections (WAN to LAN). If you wish to
allow certain WAN users to have access to your LAN, you will need to create custom rules to allow it.
See the following gure.
12.5 Enabling Firewall
The ordering of your rules is very important as rules are applied in turn.
The default rules allow LAN-to-WAN trafc and deny trafc initiated from WAN-to-LAN. You may
block trafc initiated from the LAN by conguring blocked services in the Services screen. You may
allow trafc initiated from the WAN by conguring port-forwarding rules, one-to-one/many one-to-one
mapping rules and/or allow remote management.
The rewall is automatically enabled when you congure blocked services. When you congure a
remote management menu to allow access to the 1500WR Wireless Router, a rewall rule (WAN-to-
WAN) is automatically created.

Remote Management
This chapter provides information on the Remote Management screens.
13.1 Remote Management Overview
Remote management allows you to determine which services/protocols can access which 1500WR
Wireless Router interface (if any) from which computers. You can customize the service port, access
interface and the secured client IP address to enhance security and exibility.
When you congure remote management to allow management from the WAN, you
still need to congure a rewall rule to allow access. See the rewall chapters for
details on conguring rewall rules.
You may manage your 1500WR Wireless Router from a remote location via:
• Internet (WAN only) • ALL (LAN and WAN)
• LAN only, • Neither (Disable).
When you Choose WAN only or ALL (LAN & WAN), you still need to
congure a rewall rule to allow access.
To disable remote management of a service, select Disable in the corresponding Server Access eld.
13.1.1 Remote Management Limitations
Remote management over LAN or WAN will not work when:
1. A lter in SMT menu 3.1 (LAN) or in menu 11.5 (WAN) is applied to block a Telnet, FTP or Web
service.
2. You have disabled that service in one of the remote management screens.
3. The IP address in the Secured Client IP eld does not match the client IP address. If it does not
match, the 1500WR Wireless Router will disconnect the session immediately.
4. There is an SMT console session running.
5. There is already another remote management session of the same type (web, FTP or Telnet)
running. You may only have one remote management session of the same type running at one time.
6. There is a web remote management session running with a Telnet session. A Telnet session will be
disconnected if you begin a web session; it will not begin if there already is a web session.

13.1.2 Remote Management and NAT
When NAT is enabled:
• Use the 1500WR Wireless Router’s WAN IP address when conguring from the WAN. y Use the
1500WR Wireless Router’s LAN IP address when conguring from the LAN.
13.1.3 System Timeout
There is a system timeout of ve minutes (three hundred seconds) for either the console port or telnet/
web/FTP connections. Your 1500WR Wireless Router automatically logs you out if you do nothing in
this timeout period, except when it is continuously updating the status in menu 24.1 or when sys stdio
has been changed on the command line.
13.2 Telnet
You can telnet into the 1500WR Wireless Router to perform remote management.

13.6 Conguring SNMP
Simple Network Management Protocol is a protocol used for exchanging management information
between network devices. SNMP is a member of the TCP/IP protocol suite. Your 1500WR Wireless
Router supports SNMP agent functionality, which allows a manager station to manage and monitor the
1500WR Wireless Router through the network. The 1500WR Wireless Router supports SNMP version
one (SNMPvl) and version two c (SNMPv2c).
The next gure illustrates an SNMP management operation. SNMP is only available if TCP/IP is
congured.
An SNMP managed network consists of
two main types of component: agents and a
manager.
An agent is a management software
module that resides in a managed device
(the 1500WR Wireless Router). An agent
translates the local management information
from the managed device into a form
compatible with SNMP. The manager
is the console through which network
administrators perform network management
functions. It executes applications that
control and monitor managed devices.
The managed devices contain object
variables/managed objects that dene each
piece of information to be collected about
a device. Examples of variables include
the number of packets received, node port
status etc. A Management Information Base
(MIB) is a collection of managed objects.
SNMP allows a manager and agents to
communicate for the purpose of accessing
these objects.
SNMP itself is a simple request/response protocol based on the manager/agent model. The manager
issues a request and the agent returns responses using the following protocol operations:
• Get - Allows the manager to retrieve an object variable from the agent.
• GetNext - Allows the manager to retrieve the next object variable from a table or list within an agent.
In SNMPvl, when a manager wants to retrieve all elements of a table from an agent, it initiates a
Get operation, followed by a series of GetNext operations.
• Set - Allows the manager to set values for object variables within an agent.
• Trap - Used by the agent to inform the manager of some events.

13.6.1 Supported MIBs
The 1500WR Wireless Router supports MIB II that is dened in RFC-1213 and RFC-1215. The focus of
the MIBs is to let administrators collect statistical data and monitor status and performance.
13.6.2 SNMP Traps
The 1500WR Wireless Router will send traps to the SNMP manager when any one of the following
events occurs:
SNMP Traps
TRAP* TRAP NAME DESCRIPTION
1coldStart (dened in RFC-1215) A trap is sent after booting (power on).
2warmStart (dened in RFC-1215) A trap is sent after booting (software reboot).
3NnkUp (dened in RFC-1215) A trap is sent when the port is up.
4authenticationFailure (dened in
RFC-1215)
A trap is sent to the manager when receiving any
SNMP get or set requirements with wrong community
(password).
6NnkDown (dened in RFC-1215) A trap is sent when the port is down.
